def __init__(self, command: List[str], i: str):
        self.command = command
        # create child process attached to a pty we can read from and write to
        (child_pid, fd) = pty.fork()
        if child_pid == 0:
            # this is the child process fork.
            # anything printed here will show up in the pty, including the output
            # of this subprocess
            print("starting subprocess")
            subprocess.run(
                f"echo new-ui mi2 `tty` > /tmp/gdbguitty{i}.txt",
                shell=True,
                env={"PS1": ""},
            )
            print("cat complete, now running command")
            subprocess.run(command, env={"PS1": ""})
            print("finshed...")
            # os.execvpe(command[0], command[0:], {"PS1": ""})
        else:
            # this is the parent process fork.
